2 Parallel Misalignment Angular Misalignment Torsional Misalignment Axial Misalignment Characteristics and benefits of LF Torsional Couplings The basic component of the Torsional coupling is the unique and highly versatile elastomeric element. LF This element can be easily mounted in a number of different ways according to the application, and without special design changes or complex hardware modifications.The element, which is available in different materials for optimium performance, is connected to a cylindrical hub with radial screws and then to a flanged hub by axial screws.This unique coupling design is remarkably simple, highly effective, and gives the Torsional coupling unmatched performance capabilities.

The Torsional coupling system has readily available solutions for user requirements of misalignment, installation environmental conditions; LF corrosives, temperature, etc., torsional vibration dampening, noise reduction, reliability, reaction force reduction and more. LF Torsional couplings recognize the three essential requirements that a coupling must fulfill: 1) Reliable transmission of power. 2) Quick and economical installation. 3) Protection of the coupled equipment from dangerous torsional vibrations, reaction forces and misalignment. Application engineering and experienced customer service support this line of LF Torsional couplings. Our application engineers routinely administer computer analysis of potential torsional problems in drive systems. The considerable advantages of the Torsional coupling, as well as the service offered LF by our application engineers has led to wide use of this coupling. The L-Loc spline-clamping hub described in more detail in this catalogue virtually eliminates spline shaft wear and “fretting”. The Torsional coupling is one LF of the leading couplings in the field of hydrostatic drives in rugged off-road construction equipment.
